Mean, Median, Mode Calculator

The mean sums and divides; the median takes the middle value; the mode is the most frequent. They agree in symmetric data and split in skewed data — one billionaire in a room of hundred people wrecks the mean income but barely moves the median.

Use the median for skewed quantities (incomes, home prices, response times), the mean when values are symmetric or when totals matter, and the mode for categorical-style questions like the most common shoe size.
